The tomatoes are up and it's time to transplant. If you have started your own seeds here are a few words of advice.
Generally seedlings are pretty tough, however they still can be bent or broken and if that happens they will not produce.
Gently remove seedlings from container and shake them apart. You do not need to keep any soil on the roots.
Carefully bury the start up to the leaves, this allows roots to grow along the stem.
One word of caution.Do not use organic potting soil alone for this step. I have found that it doesn"t have enough nutrients to support the rapid growth of the plant. I use a 3 to 1 ration of farm dirt to organic potting soil.
There are alot of containers you can transplant into just be sure you have good drainage . I use styrofaom cups. I write the tomato variety on the cup with permanent marker. I re-use these cups year after year. Keep under lights until you can transplant them out into your garden.
